Due to the incompatibility in licences between glibc and newlib/cygwin, 
I have been avoiding looking at the headers directly.

That only works if the parts of our netinet/*.h which use these are 
similarly guarded, or their struct members converted to the u_intN_t 
types (as in netinet/ip6.h).  Unfortunately these headers are not well 
documented.

Could you tell me how the following are guarded:

netinet/ip.h:
* struct ip;
* struct ip_timestamp;
* IP_MAKE_VHL, IP_VHL_*
* IP_MAXPACKET
* IPTOS_*
* IPOPT_*, MAX_IPOPTLEN
* MAXTTL, IPDEFTTL, IPFRAGTTL, IPTTLDEC

netinet/tcp.h:
* struct tcphdr;
* TCPOPT_*, TCPOLEN_*
* TCP_NODELAY, TCP_MAXSEG, TCP_NOPUSH, TCP_NOOPT

netinet/udp.h:
* struct udphdr;
